Modified Winkler method for dissolved oxygen determination Abstract In this study the group has determined the presence of oxygen in sample through a modified winkler method. The amount of oxygen is determined through a series of reaction. A body of water can sustain life if dissolved oxygen is sufficed. Depletions in dissolved oxygen can cause major shifts in the kinds of aquatic organisms found in water bodies. Introduction The amount of dissolved oxygen present in water or wastewater

Book Summary Management Teams: Why they succeed or fail? The scientific research that gave birth to the Belbin Team Role theory started in the 70’s when funds were assigned to researchers from Cambridge and College of Henley to study the use of computer in management. The research started from a recurring phenomenon observed at Henley College that some teams performed better than others despite their homogeneity in terms of qualifications and experience

DATE PERFORMED: JANUARY 6‚ 2011 SPECTROPHOTOMETRIC DETERMINATION OF THE EQUILIBRIUM CONSTANT OF A REACTION ABSTRACT The objective of the experiment was to determine the equilibrium constant of the reaction forming ferric thiocyanate through the use of Spectrophotometry. For the calibration‚ five standard solutions were prepared‚ then their respective absorbance values that were obtained through the use of the spectrophotometer‚ were plotted versus the concentration of the analyte so that a calibration

The Use of Cooling Curves in the Determination of the Phase Diagram for a Lead-Tin System V.O.L.Tabell Department of Mining‚ Metallurgical and Materials Engineering University of the Philippines‚ Diliman vo_tabell@yahoo.com Abstract This paper discusses the use of the cooling curves in the determination of the phase diagram of a Lead-Tin system. The inflection points of these cooling curves were obtained by melting a series of mixtures of lead and tin at varying compositions. These critical

On the other hand‚ in the article When Self-Determination Runs Amok by Callahan‚ he explores the concept of active and passive euthanasia‚ but for him it’s not so much of an ethical debate – as it is for Rachels – but rather divides his theory into three parts. First‚ he speaks about the legitimate conditions under which an individual may kill another. Secondly‚ he speaks about meaning and limits of self determination‚ arguing that this type of view only leads to a "idiosyncratic view of the good

INTRODUCTION Alkaline phosphatase catalyses the hudrolysis of p-nitrophenyl phosphate (a synthetic substrate) at an optimum pH of 10.0 with the liberation of p-nitrophenol. The substrate is colourless‚ but the product p-nitrophenol is yellow in alkaline solution‚ absorbing maximally at 405 nrn. Thus a convenient assay for this enzyme involves monitoring the change in absorbance of the reaction medium at 405 nm. Exergonic (i.e energy producing reactions) exhibit a negative free energy change

Freewill vs. Determinism Good vs. Evil What makes a decision evil is when it is made completely with regard to others. What makes a decision good is when the person who made it can look back and feel like what he choose was wholly right. It is completely up to a person whether or not they take others into consideration or even decide to look back long enough to care‚ just like it is up to that person to choose where they go in life. Whether it’s up the "good path" or down the "evil path" isn’t
